Let's divide 42451323 by 100
We want to divide 42451323 by 100.

On to step 1:
The number 100 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 100

Going ahead to step 2:
100 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 100

On to step 3:
When dividing 424 by 100, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 400 away from 424, we end up with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 100

Going ahead to step 4:
245 divided by 100 is 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 200 from 245 to get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 100

Advancing to step 5:
If we divide 451 by 100, we get 4 and a remainder of 51.
The next digit of our result is 4. 
Result so far: 424.0
If we take 400 away from 451, we end up with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 100

On to step 6:
100 goes into 513 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 4245.0
If we take 500 away from 513, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 100

On to step 7:
132 divided by 100 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 42451.0
The remainder is 32 after subtracting 100 from 132.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 100

Going ahead to step 8:
100 can be fit into 323 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 424513.0
Subtracting 300 from 323 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
230 divided by 100 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 424513.2
The remainder is 30 after subtracting 200 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 100, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 424513.23
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
100 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 424513.23
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 424513.23
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 424513.23 with a remainder of 0.0.
